DYEING AND BLEAGHING MACHINE;

Specification of Letters Patent.

Patented Oct. so, 1917.

To all whom 2'2, may concern.

Be it known that we, THOMAs Armor and WALTER W. SnssomfofPhiladelphia, in the county of Philadelphiafland State of Pennsylvania, have invented certain new and useful Improvements in Dyeing and Bleaching Machines, whereof the following is a specification, reference being had to the accompanying drawings. 7

Our invention relates to dyeing and bleaching machines of the type in which steam is introduced into the dye liquor in the receptacle in which the goods to be dyed are immersed in said liquor. Heretofore it has been customary to introduce steam directly at or near the bottom of this receptacle from a steam pipe. The objection to this method is that if the steam is admitted too violently, it is apt to cause the liquor to boil over and scald the operator. Also the goods come directly in contact with the escaping steam which results in a tendency to strip off the color or cause streaks. It is also impossible to keep the entire body of dye liquor at a uniform temperature since the liquor is more rapidly heated at the point where the steam jet escapes.

To overcome these objections, according to our invention, the perforated steam pipe is itself inclosed within a larger perforated pipe which although receiving the dye liquor within itself, and preferably acting as the outflow pipe of the system by which the dye liquor is circulated, prevents direct contact of the goods with the steam pipe. Our invention also relates to the details of the mounting of the steam pipe and the arrangements for its ready disassembling which W111 be hereafter described.

In the accompanying drawings, Figure I, is a sectional view of the lower part of a dyeing and bleaching vat illustrating the application of our invention thereto.

Fig. II, is a cross sectional view on the line H, II, of Fig. 1.

Referring to the drawings, the dyeing receptacle 1, contains near its bottom, the large perforated guard pipe 2. The pipe extends preferably from one end of the receptacle to the other, being supported by 1ts passage through the walls of the receptacle. At one end this pipe communicates with the pump 8, by which the dye liquor is circulated, being continuously withdrawn from the receptacle by the pipe 2, and returned to it by the supply pipe not shown. The otherend of pipe 2," is provided with a flange at, to which is bolted a cap plate 5,

centrally pierced for-the reception of the steam pipe 6, which is perforated throughout its length as shown in the drawings. Pipe 6, may be closed at the end with the cap 7, which is provided as shown with an opening forming an end jet to assist the circulation. The support of the steam pipe within the larger guard pipe 2, is such as to cause it to assume an axial position therein. This is preferably accomplished by means of the brackets 8, attached to the bottom of the steam pipe and reaching to the sides of the pipe 2. The perforations of the guard pipe are larger than those of the steam pipe and are preferably arranged so as not to directly coincide therewith. A convenient way of arranging this is to place the perforations of the steam pipe in two side lines, as seen in Fig. II, and the perforations of the outer pipe in a single line along the bottom of said pipe.

In operation, the dye liquor is sucked into the pipe 2, by the pump 3, and thence returned to the receptacle by way of the supply pipe not shown. Steam is discharged from the perforations of the steam pipe and efiects the heating of the liquor within the pipe 2, being for the most part intermingled therewith before the liquor is returned to the dyeing receptacle. The pipe 2, enveloping the steam pipe effectually prevents the goods bolting of the cap plate 5, from the flan ed head of the pipe 2, permits the steam plpe with its supporting brackets to be readily and freely withdrawn.

Having thus described our invention, we claim:

1. In combination with the dyeing recep- 15 tween the Walls and tacle, a perforated pipe traversing the same, and a smaller perforated steam pipe received Within said large-r pipe and thereby kept from contact With the goods which are be dyed Within the dyeing receptacle.

2. In a dyeing receptacle, the combination of a large perforated outlet pipe horizontally supported between the Walls of said receptacle near the bottom thereof, and a smaller 13 perforated steam pipe supported axially Within, said larger plpe.

3. In a dyeing machine, the combination of the dyeing receptacle, a large perforated pipe supported thereof, an annular collar constituting the closure for one end of this pipe, a perforated steam pipe received Within this collar and located along the axis of Copies of this patent may be obtained for: five cents each, by addressing within the same, and ber JAMns H.
